The four-time world champion complained of what was originally thought to be a problem with his car's front suspension.

Sebastian Vettel, who missed out on beating Lewis Hamilton to a fifth world title, sent an unexpected message on Ferrari team radio on Friday. During the second practice for the Brazilian Grand Prix, the four-time world champion complained of what was originally thought to be problems with his car's front suspension. "There's something loose between my legs," Vettel supplied additional impromptu detail when he told the team. "Apart from the obvious. Something is flying around my feet. I'd be proud if it was what you think it is, but it's not."

Vettel's radio message had some really funny reactions from Formula One fans.

The mischievous Vettel later joked during an interview that the Interlagos circuit was bewitched and had a spell cast on it.

Ferrari must out-score Mercedes by 13 points in Brazil to keep the title battle alive and hope they can end this year in encouraging fashion before a reshuffle of their line-up next year will see Monegasque Charles Leclerc arrive as the new team-mate for Vettel.
